Dynamic C 9 Release Notes

Dynamic C 9

Version 9.62A (August 2020)

INTRODUCTION

These are the release notes for Dynamic C 9.

Dynamic C 9 is the IDE (Integrated Development Environment) for Digi International's core modules and single-board computers based on Rabbit 2000 and 3000 processors.

The IDE includes a graphical editor and debugger, a command-line compiler, and a graphical tool (Rabbit Field Utility) for installing compiled binary firmware to a serially-connected device.

KNOWN ISSUES

  1. Unsupported page number formats may crash DC. For example, %t is not supported in the Page Number Text field of the Page Setup dialog.

  2. A terminating program can have debugging problems if a breakpoint is set on the first line when the program starts or restarts. With no breakpoint at the first line all debugging behaves normally.

  3. A boolean comparison, e.g. lhs < rhs, will generate incorrect code if lhs is an (unsigned) long array by type or by cast, and rhs is a multi- dimensional array of any type in which the lowest dimension index is an expression of variable(s) and constant(s), e.g. LongArray[0] >= Array[0][i + 1]. The workaround is to enclose rhs in parentheses. Correct code will be generated for LongArray[0] >= (Array[0][i + 1]). Note that correct code is generated for LongArray[0] >= Array[0][i + j] because the lowest index expression does not involve any constants.

  4. Source code lines in program files (.c extension) can be of any length beginning with version 9.60, but the 250 character maximum line length remains for library files.

  5. The sizeof(nonExistentStruct), where nonExistentStruct has no definition, evalutes to 0 instead of producing a compile error as it should.

  6. The data type for xstring or xdata entries in an xdata statement can be cast to long without compiler warning or error, but the type will always be long *, and will occupy 2 bytes, not 4, for a root address which contains the xmem address of the entry. If one creates a struct into which the xdata entries are read, fields for xdata or xstring entries need to be long *. See sample program xmem\xdata.c for an example.

  7. Stack relative addressing in an assembly statement, such as

    ld    iy, (SP+@SP+VarName)

    is limited to 255 bytes. If VarName is more than 255 bytes deep in the stack this will compile without warning or error but will retrieve the data that is the actual depth modulo 256. The following workaround is always safe:

    ld    hl, @sp+VarName
add   hl, sp
ld    hl, (hl)
ld    iy, hl

  8. Memory leaks lose about 4Kbytes per compile. Close and re-open Dynamic C periodically to avoid problems.

  9. A function returning a struct does not work correctly from within a cofunction. Values copied into the local structure will be set incorrectly.

  10. A C statement with only a semicolon within a #asm block does not compile if the block is within a global #asm defined function. The "c ;" in section 13.1.3 of the Dynamic C manual does compile and is within a #asm defined function but that function is within a C defined function. Using "rst 0x28" is a suitable substitute for "c ;" within any #asm block.

  11. An array can be used to initialize a type compatible constant pointer, unless the array is a struct member. A workaround for this case is to initialize the pointer with the address of the struct member array which will assign the expected value to the pointer and the program will run as expected despite a warning about a type mismatch.

    struct {
    int memberArray[];
} s;

int globalArray[];

int * const pInt = globalArray;    // ok
int * const pInt = s.memberArray;  // results in an error
int * const pInt = &s.memberArray; // workaround

  12. A debug timeout target crash may occur after hot-swapping a smaller xD card for a larger xD card using the presently documented method. For a workaround to this problem, please refer to sample program FAT\fat_hot_swap_3365_75.c. Note the added comments and call to the low level, undocumented _fat_config_init() function.

  13. In debug run mode (as opposed to stand-alone run mode) following a program termination caused by a run time exception, the Dynamic C debug kernel does not always correctly restart an application subsequent to a normal program termination. Symptoms can include an apparent application hang, non-clearing of STDIO window content before adding new content, unhandled RST38, etc.

    To work around the problem the application program should not be allowed to terminate normally in debug run mode. When testing small sections of code which include the possible generation of run time exceptions, adding a while (1) ; loop as necessary to prevent application termination can be helpful. Then, in order to restart the test code for another debug session, type Ctrl+Q to stop program execution in the debugger followed by Ctrl+F2 to reset the execution cursor back to the start of main().

    Note that a typical embedded application does not terminate in normal operation.

  14. Sample program Samples\RCM3300\Module_Integration\integration.c does not run properly when run with Down Load Manager support.

  15. The command-line compiler will not emit warnings and errors when compiling to a binary file. The workaround is to compile to an attached target using the "-n" command-line option for a "Null compile/syntax check without running". If the compiler does not emit any errors, re-compile with one of the binary output options (-b, -br).

  16. On the BL2600 SBCs, there is some overlap of calibration constants stored in the UserBlock. If you need to access both:

    • single-ended unipolar channels 2 to 7 with gaincode 7 and
    • single-ended bipolar channels 0 to 5 with gaincode 0

    you will need to define macro BL26XX_CAL_ADC_OVERLAP_FIX in your programs and re-calibrate the affected unipolar channels with gaincode 7 and ALL of the bipolar channels with all gaincodes.

  17. Dynamic C 9 supports SSL 3.0 and TLS 1.0, but major web browsers are due to require TLS 1.2 or later by the end of 2020. Users who require secure connections will need to use older web browser versions that still support TLS 1.0, or switch to Rabbit 4000 or 6000-based hardware and make use of Dynamic C 10's TLS 1.2 support.

  18. When generating .HEX files, the compiler incorrectly pads the length to a multiple of 32, using bytes from the previous block of 32 bytes. The generated .BIN file is the correct length and contains a complete firmware image.

  19. Since Dynamic C 9.30, assigning an 8-bit value to a 16-bit variable via a pointer will generate a bad opcode sequence, similar to the following example:

    3A18BA   ld a, (0xBA18)                 9
6F       ld l, a                        2
2600     ld h, 0x00                     4
DDF400   ld (hl + 0), hl                13

    Please see #9 for details on the issue, including methods to identify .BIN or .LST files with the sequence, along with source code workarounds and a method to patch .BIN files if recompiling isn't an option.

UPDATE CONSIDERATIONS

If updating an existing installation of 9.62 or earlier via the Dynamic C 9 GitHub repository, you should manually apply the changes in ucos2.patch, found in the Dynamic C installation directory. The Dynamic C 9.62A (and later) installers include the patched file.

UPDATE BEST PRACTICES

Digi recommends testing the new release in a controlled environment with your application before you deploy firmware to production devices.

CHANGE LOG

9.62A (August 2020)

This is a recommended release.

The big change for this release is that Dynamic C is now an Open Source project on GitHub. It includes source code to the previously-encrypted SSL libraries, and the license was changed to MPL 2.0 (Libraries) and ISC (Samples).

This release was made as 9.62A since it does not include changes to the compiler and only contains modified libraries, samples and documentation. It uses shortcuts (.lnk files) to launch the compiler with a command-line parameter of -c A, forcing the compiler to identify itself as 9.62A and use registry entries for version 9.62A.

Note that the bugfix for DC-391 below is included in the Dynamic C 9.62A installer, but included as a patch in the GitHub repository due to licensing issues with the uC/OS-II code. View ucos2.patch for instructions on how to apply it.

Users of the SSL/TLS code in Dynamic C 9.62A should be aware that it only implements TLS 1.0 and there aren't plans to update it to TLS 1.2. End users may not be able to access https webpages hosted on Rabbit 3000 products as web browsers deprecate support of TLS 1.0.

NEW FEATURES

  • Incorporates Serial Flash update (40002882_A) for revision E of 45DB641 chips used in new hardware. See PatchNotes_SerialFlash.txt for details.
  • Add Samples/extract_flash.c to download firmware stored on device flash.
  • Add SFLASH_ERASE.C sample for RCM33xx and RCM37xx to erase serial flash.

BUG FIXES

  • DC-73: fix calculation of XMEMORYSIZE in StdBios.c for FAST_RAM_COMPILE mode.
  • DC-207: Correctly render SSI/RabbitWeb (shtml/zhtml) tags spanning multiple 256-byte blocks in files on FAT filesystem.
  • DC-260: Improve ASIX Ethernet link recovery by allowing more time to establish link after turning PHY back on (8s vs. 2s).
  • DC-283: Repeatedly setting a gateway then deleting all routers no longer fills APR cache.
  • DC-358: Create ZNETSUPPORT.LIB from subset of remoteuploaddefs.lib to allow use of zconsole apps on non-RCM3300 hardware.
  • DC-391: Usage of OS_TASK_OPT_STK_CLR with OSTaskCreateExt() would erase an extra byte after the stack. For stacks ending at a 64KB boundary (e.g., 0x6FFFF), it would wrap to 0 (e.g., 0x60000).
  • RCM-94: support 45DB642D serial flash devices with 1024-byte page size.
  • RCM-126: add RCM3900/disable_ethernet.c to disable ASIX Ethernet when not using TCP/IP. Chip generates excess heat if not initialized at startup.
  • Fix ASIX.LIB error in patch2 that broke link recovery code.
  • Fix %g formatting error for floats smaller than 0.1 (backported from Dynamic C 10).
  • Fix "compile to RAM" on RCM3750 by updating _Get_Stack_Size() which failed for physical addresses larger than 1MB.
  • Fix Timer A registers used in pktEopen() of PACKET.LIB.
  • Don't allow expiration of existing ARP entry in router_add() (backported from Dynamic C 10).
  • Backport changes from Dynamic C 10 to fix duplicate ACK and keepalive issues in TCP.LIB.

OTHER FUNCTIONAL CHANGES

  • Document known issue #15 with the command-line compiler not emitting warnings/errors for "compile to binary" mode.
  • Document known issue #16 and provide work-around for overlapping calibration constants on BL26xx SBCs. (DC-276)
  • Add Function Help (CTRL-H) for _xalloc().

9.62 PATCH UPDATE 2 (February 2013)

NEW FEATURES

  • The Lib\NandFlash\nflash.lib driver library has been updated with support for Micron/Numonyx/ST NANDxxxW3A nand flash devices. Previously supported nand flash devices, used on e.g. RCM3365 and RCM3900 boards, have been discontinued and are no longer available. As of 01-Dec-2012, new production e.g. RCM3365 and RCM3900 boards will have a Micron/Numonyx/ST NAND256W3A (32MB) nand flash device installed.

    Custom applications which use nand flash, whether based on e.g. RCM3365, RCM3900 boards or a custom nand flash board design, should be recompiled using Dynamic C 9.62 with this PATCH UPDATE 2 installed in order to support the new, increased selection of small-block nand flash devices.

  • Includes the content of an earlier patch which adds support to Dynamic C 9.62 for a new BL2600Q board type, product ID 0x170F, comprised of an RCM3900 installed into a BL2600 base board. Please refer to the README_BL2600Q_PATCH.TXT file for details.

BUG FIXES

  • Defect 20311 patched. On boards such as the OP6700 or TCP/IP Dev Kit, the MAC address was not being read from the serial EEPROM.
  • Defect 20900 patched. When UDP send functionality's ARP resolution fails it now correctly releases its ARP table handle.
  • Defect 31569 patched. When ARP.LIB functionality detects an IP conflict with a remote host, the response is now correct for either gratuitous or normal ARP requests.
  • Defect 31780 patched. Multicast ARP table entries are no longer purged.
  • Defect 32677 patched. Rabbit 3000A's SSL now works with Firefox and Safari web browsers.
  • Defect 42241 patched. Rabbit now responds correctly to ARP probes (i.e. "who has IP w.x.y.z?" Ethernet broadcast) from source IP 0.0.0.0.
  • Defect 42695 patched. A two-flash (i.e. 2*256K flash devices on board) DLP now has the full 256K secondary flash size available for program code.
  • Defect DC-4 patched. HTTPC.LIB's HTTPC post functionality, following a successful post operation, sets HTTPC_STATE_HEADER state.
  • Defect DC-19 patched. The ASIX PHY link-fail bug work-around, broken in 9.62 PATCH UPDATE 1, is fixed. Ethernet link is restored within a few seconds of cable reconnection after either a lengthy (approximately 20 minutes or more) cable disconnection or a series of repeated quick cable disconnection, reconnection events.
  • Defect RCM-7 patched. Prevent reset of a TCP connection's keep-alive timer in the case that a previously connected remote host attempts to establish a new connection which re-uses its previous TCP connection's source and destination IP addresses and port numbers.
  • Defect 42746 patched. The Samples\xalloc_stats.c standard sample program no longer reports an error due to calling xalloc_stats() with a zero parameter.

OTHER FUNCTIONAL CHANGES

  • In tcp_config.lib, the _PRIMARY_STATIC_IP and _PRIMARY_NETMASK macro definitions are now conditional to prevent warnings when overridden by custom definition(s). The default definitions remain the same, "10.10.6.100" and "255.255.255.0" respectively.

  • Defining DO_NOT_WARN_ON_RT_FULLDUPLEX before #use dcrtcp.lib prevents a warning in REALTEK.LIB when RT_FULLDUPLEX is also defined.

9.62 PATCH UPDATE 1 (June 2011)

NEW FEATURES

  • This patch includes a previous patch to add BL2600Q (an RCM3900 installed into a BL2600 base board) support to Dynamic C 9.62. See README_BL2600Q_PATCH.TXT in the main Dynamic C 9.62 installation folder for details.

  • Two different new behaviors are available after a BIN file is loaded to the Rabbit target via the RFU:

    1. When RFU_BIN_WAIT_FOR_RESET is defined, after the BIN file is loaded via the RFU the application will not run until the programming cable is disconnected and followed by a hardware reset.
    2. When RFU_BIN_WAIT_FOR_RUN_MODE is defined and RFU_BIN_WAIT_FOR_RESET is not defined, after the BIN file is loaded via the RFU the application will not run until the programming cable is disconnected.

    An easy place to define the desired new macro to control BIN file behavior is in Dynamic C's Project Options' Defines box. Note that when neither RFU_BIN_WAIT_FOR_RESET nor RFU_BIN_WAIT_FOR_RUN_MODE are defined, Dynamic C 9.62 behavior is per its usual. Also note that compiling in debug mode when either of these macros is defined will result in a "helpful" error message.

  • Added HTTP client support via the new Lib\tcpip\httpc.lib library. See also the new Samples\tcpip\http\http_client.c sample program.

BUG FIXES

  • Defect 21640 patched. Stack(s) are now allocated more space-efficiently, using _xalloc()'s alignment capability. Also, the correct value is assigned to the global BaseOfStacks1 variable.
  • Defect 24080 patched. SERLINK.LIB's ppplink_asymap() function now respects the peer's asynchronous serial escape character table setting.
  • Defect 24260 patched. Updated WIEGAND.LIB's wiegand_init() function to always call the appropriate SetVectExternX000() and the SetVectIntern() functions.
  • Defect 24421 patched. The errmsg.ini file and the ERRNO.LIB and ERRORS.LIB libraries are patched to add ESHAREDBUSY (240) and EFUNCBLK (243) error codes and to make the EFATMUTEX (300) error code consistent throughout.
  • Defect 24430 patched. Corrected the OP68xx.LIB library's brdInit() function help descriptions of PC0,1 (serial port D, RS485) and PD4,5 (serial port B, RS232).
  • Defect 24474 patched. Improved the COSTATE.LIB library's DelayTicks(), DelayMs() and DelaySec() function help descriptions.
  • Defect 24475 patched. Improved the COSTATE.LIB library's IntervalTick(), IntervalMs(), and IntervalSec() function help descriptions.
  • Defect 24477 patched. The COSTATE.LIB library's DelayTicks() function is patched to accept a longticks delay parameter. This matches all otherDelay*()andInterval*()` firsttime functions.
  • Defect 24743 patched. The PowerCoreFLEX.LIB library's switchIn() function now causes a -ERR_BADPARAMETERrun time error to occur if itsswin` parameter is invalid.
  • Defect 25077 patched. A work around in IP.LIB's internal is_nonlocal_subnet() function allows multiple PPP interfaces (e.g on serial ports B and D) to work correctly.
  • Defect 25307 patched. SERLINK.LIB's serial ISR now preserves XPC.
  • Defect 25613 patched. The REALTEK.LIB's internal emu9346_clk() function is updated to prevent the possibility of an asm jump out of range error.
  • Defect 25727 patched. The RNET.LIB rn_find function() now correctly searches for Rabbitnet device(s) on the specified RabbitNet port(s).
  • Defect 25750 patched. The FAT.LIB library's fat_Truncate() function's ordering of FAT code checks is updated to work around a truncation bug caused by a mixed-type comparison (long vs. unsigned long) of the negative FAT code vs. the non-negative current file position.
  • Defect 25944 patched. The WEIGAND.LIB library's weigand_init() function now correctly supports either of the input capture 1 or 2 options on Rabbit 3000 targets.
  • Defect 26212 patched. The RNET_KEYIF.LIB library's void rn_keyUnget() function no longer attempts to return a value.
  • Defect 27167 patched. The BOOTP.LIB library's dhcp_init() function now preserves DHCP options requests.
  • Defect 27247 patched. Dynamic C's LIB.DIR file has been updated to remove the reference to a non-existent RN_CFG_RCM39.LIB.
  • Defect 27384 patched. The Remote Application Update (RAU) now correctly supports customizing the number of DLP images that may be stored.
  • Defect 27692 patched. The IX register's content is now preserved by SYS.LIB's updateTimers() function.
  • Defect 28314 patched. The STDIO.LIB library's snprintf() function now always null-terminates its output buffer.
  • Defect 28403 patched. The RCM3300 Remote Application Update (RAU) DLM / DLP shared network information save / restore feature now works correctly.
  • Defect 28846 patched. Rabbit boards equipped with an ASIX 10/100 Ethernet device and connected to some models of network switch (e.g. Foundry Fastedge X448, Linksys EF3124, Linksys EZXS55W) now reliably recover link after the Ethernet cable is disconnected then reconnected.
  • Defect 29196 patched. UCOS2.LIB's ISIntExit() is patched to prevent possible errant task switching if OSLockNesting && --bios_intnesting == OSLockNesting.
  • Defect 30070 patched. Mem.lib's _rs_xalloc_init() function is patched to work around a Dynamic C compiler ORG table problem with non-flagged battery backable RAM in "Compile to Flash, Run in RAM" compile mode.
  • Defect 30489 patched. The BL26xx.LIB's brdInit() function now handles PD2 correctly for the BL2600Q's SD card detect. (A previous patch to Dynamic C 9.62 was provided to support the BL2600Q - an RCM3900 core on a BL2600 base board.)
  • Defect 31863 patched. The GRAPHIC.LIB's TextBorderInit() function help is updated to reflect a GRAPHIC.LIB code patch to correctly handle either a NULL or an empty (i.e. "") string passed in as the title parameter.
  • Defect 32281 patched. FTP_CLIENT.LIB is updated to work with the IIS FTP server by discarding any extra arguments in the response to Rabbit's QUIT.
  • Defect 32434 patched. SDFLASH.LIB's sdspi_get_csd() function now supports SD cards that use CRC7 instead of CRC16 in their CSD block.
  • Defect 32470 patched. Serial data flash sizes in SFLASH.LIB's sf_devtable[] information array now reflect the full number of pages on each of the supported devices.
  • Defect 32937 patched. Corrupted FAT MBR information no longer causes a divide by zero run time exception.
  • Defect 33853 patched. All serial ports' initialization in SERLINK.LIB now reads SxDR four times, which suffices to clear any possible pending data in any serial port.
  • Defect 34017 patched. ZSERVER.LIB's sspec_changefv() no longer truncates maximum-length string type form variables to be one less than the maximum specified length.
  • Defect 34070 patched. In non-blocking FAT mode, a fat_Truncate() call to within a file's first cluster followed by a fat_Close() call no longer hangs with a permanent -EBUSY result.
  • Defect 35373 patched. Rabbit applications which do not have a battery-backed RTC may see an incorrect result at start up from the BIOS's bios_divider19200 and freq_divider calculations. To prevent this baud rate miscalculation, non-battery-backed RTC Rabbit applications should now be compiled with ROBUST_NON_BB_BAUD_RATE_CALC added into Dynamic C's Project Options' Defines box.
  • Defect 38754 patched. RS232.LIB's ISRs now perform ipres as the very last op-code before returning to pre-interrupt code. This prevents any possibility of contributing to gradual stack overflow.
  • Defect 38777 patched. When uC/OS-II is used, SERLINK.LIB's ISR now prevents task switching while interrupt processing continues with reenabled interrupts.
  • Defect 39302 patched. In modbus_master.lib, custom _initMBMpacket() functionality is restored for TCP-only Modbus master boards. A library function stub is now provided, along with function help.
  • Defect 39386 patched. Updated HTTPC.LIB's httpc_post_ext() and httpc_postx_ext() functions to prevent errant compile-time errors.
  • Defect 25978 patched. The Samples\FileSystem\FAT\fat_write_mbr.c standard sample program's instructions for erasing a serial flash's previous partition information now specify clearing pages 0 through 5, inclusive.
  • Defect 26635 patched. The stock RabbitLink\clear_param.c (utility) and RabbitLink\download.c (firmware) programs now compile cleanly, without warnings or errors.
  • Defect 26636 patched. The RabbitLink\download.c (firmware) program now compiles without error when its USE_DHCP macro is commented out.
  • Defect 27230 patched. The Modbus (former module) Samples\Modbus standard sample programs and a Modbus-related executable utility program are supplied.
  • Defect 27289 patched. The Samples\FileSystem\FAT\fat_write_mbr.c standard sample program now explicitly disallows partitioning of an SD card flash memory device.
  • Defect 36077 patched. The Samples\OP7200\Calib_Save_Retrieve\savecalib.c standard sample program's serial cable connection instructions now refer to the appropriate header (J10).
  • Defect 38736 patched. The Samples\OP7200\LCD_TouchScreen\cal_touchscreen.c standard sample program now enables the backlight and sets the screen contrast to avoid a blank appearance.

9.62 (May 2008)

BUG FIXES

  • Defect #25923 fixed. Corrected .c part of file mask for grep.
  • Defect #25748 fixed. Corrected initialization of RCM3900 and RCM3910 boards' SD card select and SD card detect lines.

9.60 (February 2008)

BUG FIXES

  • Defect #24366 fixed. TCP connections to peers with large receive windows no longer time out or reset.
  • Defect #24941 fixed. The built-in uCOS-II statistics variables are now correctly initialized when used, so the OS_TaskStat() function now always provides a reasonable OSCPUUsage value.
  • Defect #24990 fixed. Incorrect #asm block accesses of the auto int statusbyte variable in the Lib\RabbitNet\RNET_KEYIF.LIB library's rn_keyProcess() function have been fixed. As a result of this fix, the Samples\RabbitNet\RN1600\zmenu.c sample now works correctly when making keypad menu selections.
  • Defect #25085 fixed. Partition begin / end tests in PART.LIB's mbr_ValidatePartitions() function now work correctly. A code generation problem work around is implemented for boolean conditional expressions which reference multi-dimensional arrays of long integer type where a non-constant expression is used to calculate at least one of the indices. The work around is to encapsulate such references in parentheses and explicitly cast the reference to the appropriate long integer type within the encapsulating parentheses.
  • Defect #25143 fixed. In non-blocking mode, FAT.LIB's fat_ReadDir() function no longer returns success (0) when zero bytes are read from the directory entry. In this case, fat_ReadDir() now correctly returns -EBUSY.

9.52 (February 2007)

BUG FIXES

  • Defect #19939 fixed. Improper code generation with constant indicies in parenthesis used with multi-dimensional arrays now generates a warning. A workaround is detailed in the ReadMe.txt file.
  • Defect #20472 fixed. PPP serial more reliable with bad link quality.
  • Defect #81727 fixed. OP72xx.LIB serMode() function now always returns the appropriate result code.
  • Defect #81695 fixed. Added check for years entered as more than 2 digits. Added date range notification to stdio window.

9.50 (September 2006)

NEW FEATURES

  • Added the error_message function to errors.lib. This function returns a descriptive string in xmem corresponding to an error code.
  • New sample tcpip\http\cgi_concurrent.c demonstrates how to manage concurrent CGI instances accessing a single shared resource, including proper behavior when the HTTP connection aborts.

BUG FIXES

9.41 (February 2006)

NEW FEATURES

  • Samples, libraries and documentation added to support the new customizable RabbitFLEX boards.
  • Dynamic C's LIB.DIR library files list mechanism now searches for library files within a specified directory tree. The option to specify a complete or relative pathlist to each individual library file remains. Note that each library file name must be unique, regardless of whether the library is explicitly specified or is found via searching a specified directory tree. Also note that this feature was actually implemented in Dynamic C 9.30.

9.40 (January 2006)

NEW FEATURES

  • Libraries and documentation updated for the OP7200 family, which has a new LCD controller. The updated libraries work with both old and new versions of the OP72xx. A BIN file created using the new libraries will also work with both old and new versions of the OP72xx. (Note that the old libraries will not work with the new OP72xx.)
